Convert one astronomical unit to Solar diameters

Explanation

To convert one astronomical unit to Solar diameters all we need is to know the conversion factor and we are done. Luckily, we can compute that factor using the units' definitions below.

The result is that there are approximately 107.5161 Solar diameters in 1 astronomical unit.

Formula

1 au ≈ 107.5161 Solar diameters

symbol	au

The astronomical unit (au) is a unit of length used in astronomy.

One astronomical unit is roughly equal to the distance between Earth and the Sun.

The unit is used to measure distances at the scale of solar systems. For example, Jupiter is approximately 5 au from the Sun.

Definition of the astronomical unit

The astronomical unit is defined as exactly 149597870700 meters.

One astronomical unit is approximately equal to:

Some Facts

If the Sun were to be erased from reality, we would realise it 8 minutes and 20 seconds later, it is the time that light and gravity from the Sun take to reach us. During all that time, the Earth would continue on its orbit around an empty part of space as if nothing happened.

Solar diameters

dimension	length
synonyms	Sun diameters

This unit represents the diameter of the Sun.

The Sun is the star at the center of the solar system.

It is a giant ball of plasma powered by nuclear fusion in its core. This plasma is composed of hydrogen at roughly 73% and helium at 25%.

The Sun is a relatively small star classified as a yellow dwarf, but still contains about 99.86% of the total mass of the solar system.

Value

The mean diameter of the Sun is 1391400 kilometers.

The diameter of the Sun is roughly equivalent to:

Some Facts

The Sun is so big if you were running on its surface in a straight line at 7 km/h, it would take you more than 70 years to come back where you started (assuming you possess a technology preventing you from being instantly vaporized, otherwise you would not make it very far).
